ignoring the four vs two stroke debate, can this be run?

[BigAl]

1.8kw and 32kgs certainly wouldn't be competitive imho, although they do have an automatic gearbox?

Nzmmrc rules require a centrifugal clutch so couldn't currently race. But they could still be a good play bike for track days like Mt Wellington.

They have been racing 4 strokes overseas for awhile now and they will inevitably start to appear here, but as to what class they'd be in???

Any other thoughts out there???

it would be very very slow i mean daytona is as slow as im willing to go.....

i rode a 1.5hp goped around mt wellington and honestly it would of been better walking......the straight seems like an endless road.....


and yess their automatic

It may be ok but like Al said not a curent class for it being it has a gearbox. The 4 stroke bike raced over seas is a Panzini it's a 70cc engine and is at the same leavel as a 50cc open 2 stroke.
